i will put a 7 only because of the entirety of the story, if I had to be completely honest the ending was shit, the last half a chapter was worst than bleach in my eyes . (score 3 or 2 ) The story was quite simular to Pun Pun but if a teenager wrote it. The last arc was scattered and incomplete leaving me with a lot of question marks. It started really good problems arised at around chapter 160 in my honest opinion. If only it lasted another 4 chapters to to define and outline like 2 things it would had been a solid 8 . I couldmaybe suggest it till a certain point of the story but u could drop it a couple of arcs before.
Overall ima kms🌈
